There are mainly two types of achievements in this part: Speedrun and Minimum Moves. Other than these achievements, there are two unique achievements and a participation trophy:

Everyone's A Winner Baby
Winning a race for the first time

• You just need to finish a level for this achievement.

Hopscotch
Jump on certain cubes in sequence

• This achievement requires you to go to the right side after first jumping sequence in "Ruin Rush". Then you need to raise the red block at least twice to spawn low gravity boost. With the help of the boost, you need to cross pillars by stepping on them and you are aiming to reach to the left side. Achievement will unlock after picking up the time boost. Check the guide at the Speedrun for visual aid.

Whatever Floats Your Boat
Don't touch the floor

• You need to finish "Hover Headway" without touching the ground between the green checkered bars. Check the guide at the Speedrun for visual aid.

If you think it is too hard for you, you can use a save file to unlock speedrun achievements. Check the other section for save files.

All Rounder

• You need to earn gold medals in every level. It isn't hard as it's sound. You will unlock this when you have completed all of the speedrun achievements.
